PRINTING-PRESS GUIDE.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed September 5, 1908. Serial No. 451,783.

To all whom it may concern:

Be it known that I, EDWARD O. ANDERSON, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Printing-PressGuides, of which the following is a specification.

My invention has relation to sheet guides for use on printing presses;and it contemplates the provision of a guide designed more particularlyfor employment on conventional cylinder presses and constructed with aView of enabling the press feeder to see every sheet that is fed, ofbeing quickly and easily adjusted to meet different conditions, and ofbeing generally used to advantage for color and other work.

My novel guide is designed more particularly for use as a left-handregister guide although I would have it understood that it may bereversed and used at the right; and its novelty, utility and practicaladvantages will be fully understood from the following description andclaims when the same are read in connection with the drawings,accompanying and forming part hereof, in which:

Figure l is a perspective view of the guide constituting the bestpractical embodiment of my invention of which I am cognizant; Fig. 2, alongitudinal, vertical section of the same; Fig. 8, a transverse sectiontaken in the plane of the line 3-3 in Fig. 2; Fig. 4, a front elevationof the guide, showing the relatit e arrangement of the curved directingtongue and the abutment back of the same; and Fig. 5, a transversesection taken in the plane indicated by the line 55 of Fig. 2, lookingforwardly.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is the base of the guide which is preferably in the form of a plate,slotted at a, and is designed to be attached to and adjusted on a feedboard or the like. Fixed with respect to and rising from the plate A isa cylindrical post B in which is a circumferential groove 6, for apurpose hereinafter pointed out.

In addition to the plate A and the post B, the present embodiment of myinvention comprises a standard C, a threaded rod D which extends looselythrough a smoothbore, diametrical aperture 0 in the upper portion ofstandard C, adjusting and fixing nuts E E mounted on the rod D anddisposed at opposite sides of the standard C, an abutment F, carried atthe forward end of the rod D, and a directing tongue G, carried at theforward side of the said abutment. The standard C is arranged over andis adapted to turn about the post B, and hence the parts carried by thestandard may be placed in various positions, relative to the plate A.Said standard 0 is provided at cl with a threaded aperture to receive ascrew H the inner end 'of which extends into the groove Z) of post B soas to hold the standard on the post without preventing turning of thestandard. When deemed expedient the screw H may also be utilized toadjustably fix the standard to the post. In its lower end the standard 0has a vert cally disposed socket e and in said socket 1s arranged acoiled spring I the office of which is to hold the abutment F down tightto the before mentioned feed board.

The nuts E and E preferably have hubs f to extend into recesses g inopposite sldes of the standard C, and by reference to F1g. 2 it will benoted that when the nut E is separated by an intervening space from thestandard C and the nut E is turned against the standard and in adirection away from the operator, the threaded rod D and the partsthereon will be moved toward the right, and that when the nut E isseparated by an intervening space from the standard and the nut E isturned against the standard and toward the operator, the threaded rodand its parts will be moved toward the left; also, that when both nutsare set agamst the standard C, the threaded rod D will be securely fixedwith respect to the standard without liability of its position beingcasually changed.

An important feature of my invention consists in an abutment throughwhich a press feeder can see; the abutment herein employed comprising ametallic frame 2' having the inner sides of its walls inclined, abeveled pane of fine-quality glass j, and means, such for instance asspring clips 70 for retaining the pane in the frame.

The directing tongue G is in the form of a forwardly bowed spring stripwhich is connected at its upper end to the top bar of the frame '5 andbears at its lower end against the face of the bottom bar thereof. Saidtongue is obviously adapted to guide the edge of a sheet against theface of the abutment F even when the edge has a tendency to curlupwardly.

It will be readily understood by those skilled in the art to which myinvention appertains that the abutment F described is particularlyadvantageous for color work, and that when said abutment is employed thefeeder can see through it every sheet that is fed and have the same upacqacent to the near guide.

In audition to the advantages hereinbefore ascribed to my novel guide,it will be noted that the same is simple and inexpensive inconstruction, and, as a whole, is well adapted to withstand the usage towhich printing guides are ordinarily subjected.

Having described my invention, what I claim and desire to secure byLetters Patent is:

l. The combination in 'a sheet-guide, of a suitable support, an abutmentconnected with and adjustable toward and from the support; the saidabutment comprising a metallic frame having the inner sides of its wallsinclined, a beveled pane of glass disposed in said frame, and springclips retaining the pane in the frame, and directing means carried bythe abutment and arranged in front of the same.

2. In a sheet-guide, the combination of a base having a post, a standardarranged on and adapted to turn about the post, an abutment connectedwith the standard and arranged at one side thereof, and a sprilwinterposed between the base and the standard at the opposite side of thestandard, with reference to the abutment, for the purpose set forth.

3. A sheet-guide comprising a base having thereon acircumferentially-grooved post, a standard rotatable about said post, ascrew bearing in the standard and extending into the groove of the post,a spring socketed in the standard and interposed between the same andthe base, a threaded rod extending loosely through the standard andequipped with an abutment, and nuts mounted on said rod and disposed atopposite sides of the standard.

In testimony whereof I afiiX my signature in presence of two witnesses.

EDWARD O. ANDERSON.
